GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 632,340, datedSeptember 5, 1899.

Application filed October 2, 1896. Serial No. 607,6 80- (No model.)

To all whont it ntay concern.-

Be it known that I, EDWARD .1. DASOHBACH, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Gas-Stoves, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this specification, in which- Figure 1 is a verticalcross-section of my improved gas-stove. Fig. 2 is a rear view, partlybroken away; and Fig. 3 is a horizontal section on the line III III ofFig. 1.

My invention relates to that class of openfront gas-stoves wherein arear chamber for the products of combustion separated from the frontburner by an air-space is used, and is designed to improve the economyand increase the heating power of the stove by causing the products totake a circuitous path through a second chamber contained within therear chamber for the products.

In the drawings, 2 represents the face of the stove, which is upright,open at the front, and has a vertical hollow burner 3, hereinafterdescribed, and 4 is avertical rear chamber separated from the chamber 2by an intervening air-space 5, which is open at the sides and top. Thechamber 4 has at its upper end short pipes or fines 6, opposite to themouth of which is a hood 7, adapted to collect the products ofcombustion and to direct them into said flues. In the middle of thechamber 4 is a chamber 4, open at the bottom, being constituted by sidewalls 8 and an upper damper U.

10 is an outlet-flue leading from the upper part of the middle chamber 4and adapted to enter a hole made in a plate setin front of and closingan ordinary open fireplace.

The burner 3 is ahollow plate or slab having in its face perforationsarranged, preferably, in parallel rows and with intermediate strips ofasbestos fiber or the like. Gas is admitted into the burner through agas-mixer 11 of the ordinary Bunsen type, which enters theburner-chamber back of a vertical partition 12 therein. Said partitiondoes not extend to the top of the burner, but stops short thereof, andthus divides the burner internally into two compartments communirear ofthe burner face-plate.

. The operation of the apparatus as above described is as follows: Gasis admitted into the burner-chamber and draws with it a supply of airthrough the mixer. The mixed gas and air ascend in the burner-chamberback of the partition and, passing over the top of the partition, enterthe front compartment of the burner, whence the mixture passes throughthe perforations and, being ignited at the face of the burner, coversthe same with a body of flame and heats the asbestos fiber toincandescence. The products of combustion, ascending, are caught by thehood and pass through the pipes 6 to the rear chamber 4. At thebeginning of the operation of the stove the damper 9 is'preferablyopened, so that the products of combustion pass directly with a cleardraft to the outletflue 10 and thence up the chimney; but after thedraft of the stove has been well established the damper is closed, andthen, as shown by the arrows in Fig. 2, the products of combustionentering the chamber 4 must pass down below the side walls 8 and thenceup into and through the chamber 4: before passing out through the flue10. In this Way the heat of the products of combustion is well extractedand given out to the air of the room by radiation from the front, back,and

sides of the chamber 4: before they escape to the chimney.

At the lower part of the stove, covering the mixer 11 and itspipe, Iprefer to set a curved fender 12, having on the inner side a hook itgives a maximum of heat. It is very ornamental and is simple and cheapin construction.

I claim- 1. An open-front gas-stove having an upright burner at thefront, a rear upright chamber separated from the front by an airspaceand arranged to receive the products of combustion from the burner,andasecond chamber Within the said chamber having side walls and anopening remote from the entrance of the first-named chamber, the secondchamberhaving an exit-flue, whereby the products of combustion arecaused to take a circuitous path through the firstnamed rear chamber.

2. An open-front gas-stove havingaburner operation of the damper theproducts of com-- bustion can be caused to assume a direct or circuitouspath to the exit-flue, as desired.

In testimony whereof I have hereunto set my hand.
